Very smart! Those antennne, short, with a sort of disc with a short filament protruding from it, are diagnostic for two-winged flies (Diptera), athough some, such as mosquitos, have a different arrangement.

LOL!! This country bumpkin found the info in my insect book. It does not have a lot, just the most common ones, so most of the time I cannot put a name to the insects I take pictures of, but sometimes, like this, I actually find it there. Thanks Harold, I am learning a lot when people like you give me handy information like that of the antennae._________________Joan Young
